Question

The table below summarizes results for randomly selected drivers stopped by police in a recent year. Using technology, the data in the table results in the statistics that follow. chi-square statistic = 7.987, degrees of freedom = 1, P-value = 0.005 Use a 0.05 significance level to test the claim that being stopped is independent of race. Based on available evidence conclude that racial profiling is being used? Can we conclude that racial profiling is being used? A. Yes, because the P-value is greater than the significance level. B.

Explanation / Answer

here to test the hypothesis being stopped is indpendent of race the

null hypothesis H0: being stopped is indpendent of race

alternative hypothesis H1: being stopped is not indpendent of race

here P-value=0.005 is more than level of significance alpha=0.05, so we fail to accept H0 and conclude that being stopped is not indpendent of race.

right choice is B.Yes, P-value is less than the significance level
